KuCoin Exchange

$281 million of an Asian cryptocurrency exchange’s funds have been compromised in a security breach.

It detected large withdrawals of bitcoin (BTC) and Ethereum (ETH) tokens to an unknown wallet beginning.

One or more hackers obtained the private keys to the exchange’s hot wallets.

KuCoin’s cold wallets were unaffected.

Two Ethereum wallets belonging to KuCoin have sent more than 11,480 ETH, which currently trades at a price of about $350, to the Ethereum wallet address associated with the hack.

The Ethereum wallet address had also received over 150 Ethereum-based tokens worth more than $150 million from the two KuCoin Ethereum wallets.

The price of KuCoin’s exchange token KCS fell by 14% to $0.86 within an hour.
